Knetworkmanager permissions issue - Passive Mode

English Network/Internet
#1

For some reason all of a sudden kenetworkmanager starts up and shows “applet in standby mode” - tracking it down I have discovered it appears to be an issue with the user not having permission, at least per dbus messages and the error displayed when running knetworkmanager from the console.

I located /etc/dbus-1/system.d/NetworkManager.conf and edited the default profile to be allow rather than deny. That didn’t work so I googled about and say some guys had luck with adding a policy for the network group - however, I don’t believe there is a networks groups in Suse so this did nothing.

This is also a bit weird because that files seems the most logical, but then again the error specifically states:

Registered settings object  /org/freedesktop/NetworkManagerSettings

Yet no file named NetworkManagerSettings exists?

There is this: /usr/share/dbus-1/system-services/org.freedesktop.NetworkManagerSystemSettings.service
which contains:

[D-BUS Service]
Name=org.freedesktop.NetworkManagerSystemSettings
Exec=/usr/sbin/nm-system-settings --config /etc/NetworkManager/nm-system-settings.conf
User=root

Any suggestions on what I might be mising here to get this working again?

(Note - it starts up fine as the root user and I can see my wireless networks and connect, ect. It just fails when connecting
as a non-root user>)

Thank you,
Lews Therin

Anyone have a bright idea on this one? Not a huge deal, and I’m sure I’ll figure it out, but if some has been down this road before . . .

Did this happen after an update? Have a read of this thread. Maybe it offers a solution. (In particular, /etc/dbus-1/system.d/nm-applet.conf may be relevant here).
